Enterprises rely on product managers to come up with ideas and turn those ideas into revenue-generating applications to spur the next leg of growth and to create shareholder value. That’s a lot of pressure! It’s more essential now than ever before that product managers have the correct software stack to realize those ideas, which, with the world moving toward ever-faster performance and response times, means embracing an end-to-end real-time solution.

This post looks at the architecture of Heron, the real-time stream processing engine developed at and open-sourced by Twitter. The various modules in the system communicate between one another using well-defined communication protocols. As a consequence, Heron is highly extensible and allows the application developer, system administrator, or Heron contributor to create a new implementation of a specific module and plug it into the system without affecting other modules or the communication mechanisms between them.

A look at another enterprise-grade feature of Apache Pulsar: geo-replication. It is essential for enterprises today to have disaster avoidance and recovery strategies in place. Whereas other messaging systems can only replicate between two datacenters, Pulsar can scale out to as many as are needed. We will also look at the two types of geo-replication supported in Pulsar, synchronous and asynchronous, and when to use one vs the other.
